Design and Implementation of Environment Chamber for Interfacial Phenomenon Processes
(2022-08-08) Saini, Gurdeep Singh; Amirfazli, Alidad
With the goal of simulating the environmental conditions necessary for various droplet related phenomenon, a portable environment chamber was built and tested in this thesis. The “House of Quality” design methodology was used as a roadmap for the iterative design process. The chamber comprises a temperature control system, an anti-condensation system, and a humidity control system. The performance of the chamber was tested afterwards at different temperature and humidity setpoints, to quantitate the chambers working capabilities. The chamber can generate an environment inside it with a temperature range of 10 °C to 70 °C, and a relative humidity range of ambient to 80%. The chamber was benchmarked against experiments done in the literature; involving surface tension and contact angle. The experiments that were done for both contact angles measurements corroborated what was in the literature, however we discovered potential problem for literature values of surface tension at lower temperatures.
